Methodology: The median age of inventory data was calculated by determining all of the listing categories that were active during June 2011, and subtracting the date properties were listed on the site from the earlier of the following: their end listing date or the end of June, taking a median of all of the individual days on site counts, according to Realtor.com.

"This term accounts for properties that were withdrawn from a (multiple listing service) and subsequently relisted," according to Realtor.com, and the companys' count can differ from MLSs' days on market count, as it relies on when each property was added to the website and removed from the website.
